I had severe hair loss last year and i decided to shave my head clean in case hair will grow back thicker but thst was stupid idea.After shaving my hair from front and top of scalp didnt grow back like before.They are very thin.i Can see my scalp from top.Im 21 now and its seems to be like TE but its almost an year but i have got no hair on this specific area.Is there have someone who can tell me what is it? Im really worried about my hair.
